Eliminate unprocessed events:
  • Make sure that the DB\Events folder (including Debug) is empty or has minimal events stored before the upgrade
  • During the upgrade, this folder is scanned. If more than 10,000 events exist that are not processed yet, it interrupts the upgrade with a pop-up message stating:

    This ePolicy Orchestrator server has more than 10,000 unprocessed events

    NOTE: The above, might cause the upgrade process to take an exceptionally long amount of time.
